A MAS based energy-coordination by contract net protocol for connecting the production units of energy renewable based wind-photovoltaic energy storage system to Grid

A multi-agent system based energy-coordination by contract net protocol (MAS-ECCNP) is designed for to efficiently connect production units of energy renewable based wind-photovoltaic energy storage system (PUER-WPESs) to Grid. The negotiation protocol is a two-level bidding mechanism based on the contract net protocol. In the energy-coordination process, the proposed system allows the agent to cooperate and coordinate their actions taking into account their self-constraints and objective control to solve the optimal distribution plan overall energy and by the using the improved particle swarm algorithm to achieve the maximum economic benefit on the basic of stable operation. The paper presents the overall system design, the models of agents of different equipment, and overall energy optimizing coordination algorithm. An example is given to discuss the behavioral characteristics of negotiation and communication process based agent to verify that the system designed in this paper can achieve effective coordination of energy. The method adopted by this system can improve the efficiency of the overall operation and the economic benefits of REPU-WPESs.
